HANGER-BOX.

Specification of Letters Patent.

Patented Dec. 11, 1917.

Application filed may 9, 1917. Serial No. 167,558.

To all whom it may conaem:

Be it known that I, PAUL B, LmunnMANn, residing at N o. 52 Warrington place, 1n East Orange, county of Essex, State of New Jersey, have invented certain new and use ful Improvements in Hanger-Boxes, fully described andreprcsented in the following specification and the accompanying drawin s, forming a. part of the same.

his invention relates :to a hanger-box provided with a novel means of supplying oil thereto in such quantity only as will serve for lubrication without runnlng out of the ends of the box.

Such hanger-boxes are provided with seats upon opposite sides at the middle of their length by which they may be fitted between the legs of a hanger and guided in any practical adjustment that may be neces sary.

In the present construction, an oil-chamber for retaining a store of oil is provided in the middle of the hanger-box inter1nediate to the said seats, and the hangenbox has nozzles at its opposite ends containing each aicylindrical bearing-roll seat with-a collar 'at its outer end to embrace the shaft.

To avoid any escape of oil from the lowest point in this collar, the oil must be supplied to the born from a source no higher than thebottom of the collar, and to supply both of the roll-chambers equally, the sup ply should be delivered to the oiLchamber in the middle of the box.

This is' elfected by locating a pocketat the side of one of t e nozzles with its top not higher than the bottom of the collar,

and extending a passage from this pocketobliquel intothe oil chamber between the hangeregs.

Such an oblique arrangement is required by the-disposition of the pocket upon one of the nozzles as the legs of the hanger prevent itsbeing applied to the middle portion of the box.

The location of the pocket close to one of the hen er-legs permits the passage to be extende from the pocket into the central oil-chamber, by drilling a hole from the pocket obli uely info the said chamber, the outer end 0% the ho e upon the outer side of the pocket being permanently closed by a plu' after the passe e is formed.

B y this construct on, the hanger-box can be made with a contracted waist at the middle of its length, thus enabling it to fit within. a relatively small space between .two hanger-legs The construction will be understood by reference to the annexed drawing, in which Figure 1 is a longitudinal section of the hangerbox with the anti friction bearingrolls omitted; Fig, 2 is a plan f the lower part of the box with a section file han er legs; Fig. 3 is a section of thohangerox taken on line 33 in Fig. 2; and Fig. 1 is a sectionthrough one of the bearing-roll chambers taken on line 4l in Fig. 2 and 1looking toward the middle portion of the c designates the upper half or cap of the box which is connected with the lower half I) by lugs and bolts The cylindrical bearing-roll chambers cl are formed within cylindrical nozzles f at opposite ends of the contracted Waist, which has the seats 9 for the hanger-legs at its oppositesides and has the oil-chamher it between such seats.

The outer ends of the nozzles fjare provided with collars 71 adapted to snugly fit the shaft.

A partition is divides the lower part of each bearing-roll chamber from the oilchainber h, and has perforations Z to conduct oil from the oil-cha1nber into the lower part of the chamber at. The oil is supplied to the chamber h by a passage m extended obliquely from an oil-pocket 1b, which is formed upon the side of one of the nozzles next the edge of the hanger-seat.

The top of this pocket, as shown in Fig. 3, is about on a level with the bottom of the collar 2' and it is therefore impossible to supply oil to the oil-chamber it above the level of that collar and no overflow fromthe collar could therefore occur.

The passage h is necessaiiily obli us because the pocket cannot be locate either side of the oil-chamber, as it would interfere with the hanger-legs, but its location close to the edge of the hanger-leg or seat 9 permits the su ply of the oil-chamher from the outer si e of the nozzle and limits the depths of ;the oil in the chamber to the desired level.

A lid 0 is shown upon the pocket in Fig. 3, but such lid is not essential to the operation of the invention. the vforx'nation of upon the pocket at the the lid is raised, is open to inspection,

right level enables it to perform all its functions. The pocket, wheg the height of the oil in it corresponds to its height in the oil-chamber, so that the pocket serves as a gage to the depth of the oil as well as a preventive of overflow.

Two holesl are shown in cachet, the par-' titions In to deliver theoil from the oil.- chamber h, to the bedrin'g-roll chambers d; and the use of two holes is desi able because the sediment from the oil accumulates in the bottom of the. oil-chamber and might clog a single hole ifsuch iliere used. The provision of two holes thus forms tional security against any such obstruction. r

A, single hole embodies the invention, as well as an open notch in the partition, and I have therefore claimed a perforated partition as an elemcnt.of'the invention.

Having thus set forth the nature of the invention what is claimed herein is:

1.. A hanger-box having nozzles at its opposite ends containing cylindrical bean ing-roll chambers with collars at their outer ends to embrace the shaft, on oil-chamber interl'nediate to the bearing-roll chambers separated from'each by a perforated partition beneath the shaft, and a supply-pocket projected from one side of the hanger-box and having a channelcommunicating with an addi-' the said oilchamber, the top of such pocket being a trifle lower than the bottoms of the collars to prevent any oversupply of oil to the chambers.

2.. Ahanger-box having nozzles at its opposite ends containing cylindrical bearingroll chambers with collars at theironter ends to el'nbracc the shaft, vertical seats upon opposite sides of'the box between the said nozzles to receive thelcgs of a hanger, an oil-chamber within the space between the said seats separated from the bearing-roll chambers-by a perforated partition, and a supply-pocket 'projecterl from one side of the hanger-box atthe edge of one of the seats and having a channel extended 0bliquely into the oil-chamber between the seats.

3. A hangerehox divided longitudinally into a base and cnpnnd having nozzles at its opposite ends containing cylindrical bearing-roll chambers with collars at their outer ends to embrace the shaft, an oil-chamber intermediate. to the bearing-roll cl'nunbers separated from each by .a perforated. partition. beneath the shaft, and a supply-pocket projected from one side of the hanger-box and having a channel communicating with the said oil-chamber;

In testimony whereof I have hereunto set my hand PAUL B. LIEBERMANN.
